A bit more detail in tensor section
It clearly works but the writeup isn't great. Adding more details isn't
necessarily going to make it any better however...

Tensor functor gives morphisms
Thanks to Jarod Alper and Max Lieblich
We prove that a right exact tensor functor Coh(X) ---> Coh(Y) comes
from a morphism Y ---> X if X, Y are Noetherian and X is an algebraic
stack with affine diagonal. The proof is short because we use a trick to
show that a certain ring map is universally injective and then we use
descent for universally injective ring maps.
